One of my favourite feature of WhatsApp for iOS is coming to WhatsApp for Android -> “Swipe to reply”

When chatting one to one or in a group, you can simply swipe right on a message to reply to it. It’s far better and faster than long holding individual message and then selecting reply button in the menu that appears.

Doesn’t sound like a big deal at first, but once you get used to this new way, you realise what you have been missing this whole time. Comes in handy in a heated or fast-paced chat session.

Right now its available only to beta testers ( Version 2.18.300 ) and soon will be available as an update for everyone else.

You can download the beta version officially by enrolling in the beta program here -> https://play.google.com/apps/testing/com.whatsapp

WhatsApp beta has a history of being pretty stable, however, if you face any issues, you can go back to that link to exit the beta program.
